IBM IBM Tivoli Composite Application

IBM announced Thursday (7/29) that it has agreed to purchase Cyanea, an Oakland, Calif.-primarily based privately held enterprise established in 2001 that focuses on software monitoring and management software. IBM is not disclosing particulars of the transaction or pecuniary phrases.

He said the combination of the products developed by means of Tivoli and the technologies received from Candle and Cyanea allow IBM to offer customers “equipment on a common infrastructure that in reality address utility administration.”

The software developed through Cyanea isolates and determines the spot performance problems are taking spot in distributed applications, spoke of James Chong, president and chief govt officer at Cyanea, who is becoming a member of IBM.

Chong said his research and structure work set out to fill a spot he organize in resource management tools, which he stated don't sequester the issue to a particular software or deliver a resolution as to what precisely is going wrong.

“Cyanea views issues from the application point of view,” Chong mentioned. “It puts the problem in an utility context.”

with the aid of pinpointing the rigor in an application, it is less complicated to steer pellucid of bottlenecks throughout the software lifestyles cycle from structure through preservation, he referred to.

The Cyanea application works with Java, CICS and IMS enterprise functions working across mainframe and distributed computing environments, in accordance with IBM. IBM’s LeBlanc talked about that beyond Tivoli, the Cyanea expertise will even breathe built-in into IBM’s Rational and WebSphere items.

IBM and Cyanea had now not been strangers previous to the acquisition announcement. LeBlanc talked about the two agencies had been working in partnership essentially seeing that Cyanea’s inception. Chong celebrated that every one seventy five employees from his enterprise will breathe becoming a member of IBM.

For a long time, expertise specialists turned to relative frameworks from IBM Tivoli, CA, Hewlett Packard, and BMC (“The large 4”) to monitor their hardware and utility stacks. but the open supply world has caught up with these closed monitoring environments, and a task dubbed Nagios is poised to breathe the go-to platform for IT monitoring, including on IBM i.

Nagios, if you aren't typical, is a free and open source software product that provides monitoring and alerting for servers, community equipment, applications, and the array of services that organizations more and more count on. The utility –backed by the obligatory recursive acronym “Nagios Ain’t Gonna Insist On Sainthood” – turned into initially developed via Ethan Galstad again in 2002 to sprint and monitor Linux systems, which become simply starting to manufacture headway in commercial enterprise data centers.

through the years, the C-based software has been extended to aid an array of protest varieties, together with host components like processor load, disk and RAM utilization, and rig logs for a majority of frequent operating systems, together with IBM i. The lively Nagios community has created a gargantuan orbit of Nagios agents that hold prolonged the framework to an estimated 5,000 devices.

Nagios is an open source device that enables administrators to monitor their IT rig and applications.

On the community side of things, Nagios Core (because the open source product is wide-spread) monitors routers, switches, and other apparatus, and helps SMTP, POP3, FTP, and SNMP protocols, among others. everything remote monitoring will likewise breathe encrypted, and it additionally offers a plug-in that lets users create their personal monitors in numerous languages.

information gathered via energetic and passive Nagios plug-ins is routed into the Nagios server, the spot the information is sorted and signals are sent out. users can consume indicators in a lot of approaches, including via a web browser, via SMS pagers, and thru email. With an simple glance at the Nagios dashboard on a cellphone, a methods admins can perceive if critical servers, manner, and services are alive or dead.

The Nagios Core server utility likewise can work with a “round-robin database” (RRD) to simplify the storage and querying of time-collection statistics. With RRD, admins can dive deeper into Nagios facts and reflect about graphs to peer efficiency developments. And with a puny setup forward of time, Nagios can breathe configured to instantly reply to activities as they happen, or amplify alerts to other people.

corporations that covet more than what Nagios Core has to present can locate it from Nagios firms, the industrial outfit in the back of the open source mission. The St. Paul, Minnesota-based company, which employs Galstad, extends Nagios Core with a few offerings, together with Nagio XI, which features a extra extensible entrance-end and a MySQL-based again-end. Nagios XI likewise brings a better consumer journey with greater efficient graphs and stronger dashboards.

IBM i consumers can expend Nagios to monitor 15 metrics with the Nagios Plug-Ins for IBM i beta.

alas, Nagios companies doesn’t steer IBM i. however you can congregate a Nagios distribution for IBM i from a bit outfit known as overseas enterprise Machines. In 2017, large Blue shipped a beta edition of an IBM i plug-in designed to feed records from the IBM i sever into the open supply Nagios Core product or Nagios XI.

in keeping with a developerWorks web page, the IBM i Nagios plug-in collects 15 separate statistics facets from IBM i servers, including things like CPU and disk utilization, ASP utilization, number of lively jobs, and lengthy-working SQL jobs, amongst others. Some of these features are supported by the expend of SNMP, whereas others require the open source JTOpen Java toolbox to breathe rescue in.

The Nagios server itself doesn’t sprint on IBM i – at the least not yet. With the Nagios on IBM i plug-in, IBM gives clients with guidance on how to installation Nagios Core or Nagios XI on a Linux server. Technically, there may still breathe nothing stopping from a user setting up Nagios in a Linux LPAR on the energy systems server – and even for IBM to port the application to the IBM i OS by means of PASE – however that has no longer came about yet.

IBM makes the case for IBM i stores to manufacture expend of Nagios in a PDF presentation on Nagios created via IBM i company architect Tim Rowe and Wang Yun, who developed the Nagios for IBM i plug-in. while Navigator for i gives first rate coverage of IBM i-centric queues and metrics, that product doesn’t deliver consumers with any visibility of what’s happening outdoor the IBM i gadget.

consumers who buy Nagios XI can monitor IBM i metrics graphically.

Nagios, on the other hand, offers administrators and operators with a single centralized view of everything IT belongings, Rowe and Yun write. moreover the core IBM i metrics that are now accessible by means of the Nagios plug-in, IBM i clients can congregate vogue and historical facts, as well as the flexibility to configure metrics to their liking, no longer to mention the aptitude to create their personal custom plug-ins.

IBM isn’t the handiest company doing Nagios work on IBM i. a few years in the past, ShapPin Cheng launched a GitHub assignment known as check_as400 that moved information from IBM i server logs into Nagios. when you deem that the extensibility and openness of Nagios, it wouldn’t breathe surprising to spy independent utility providers within the IBM i group adopt the technology for their own techniques monitoring offerings.

For now, IBM offers the Nagios plug-in as a beta. Don’t breathe shocked to spy it become a totally supported offering within the months to return, particularly considering that the like affair that IBM has with open supply application at the present time.

The improvements, introduced on the 2007 Governance & risk administration Summit in Sanya, China, construct upon IBM's powerful dedication to deliver protection and company resilience through its IBM Mainframe z/OS as well as up to now introduced offerings.

"these days we're strengthening gadget z administration with more suitable tools and an intuitive, effortless to expend interface for the most demanding computing environments," referred to John Kogel, VP of Tivoli building. "Tivoli utility operates as the 'brains' behind the mainframe. We're helping consumers with efficiency and functions management, rig and workload automation, network and storage management, economic and usage reporting and protection administration."

IBM is the market salary leader in performance and availability management utility for 2006, in accordance with the analyst enterprise IDC. In its August 2007 document, "international efficiency and Availability management application 2006 dealer Shares," (IDC document #208193), IDC stated how IBM led in market share for efficiency and availability administration software in addition to experience automation utility.

As an extension of IBM's $a hundred million Mainframe Simplification funding introduced in 2006, the brand fresh application portfolio helps device z purchasers exploit more and more intricate and inter-based applications. via open requirements, the Tivoli enhancements bring fresh tiers of productiveness while safeguarding the safety of their facts. fresh capabilities equivalent to Tivoli OMEGAMON XE for CICS Transaction Gateway and Tivoli Composite application manager for SOA permit shoppers to roll out fresh business purposes hastily.

Tivoli OMEGAMON XE for CICS Transaction Gateway helps customers proactively control critical workloads and resources. here is specifically vital as more businesses depend on composite purposes that access mainframe materials.

New tools are available to assist in the diagnosis of intricate network-based applications running over the LAN. These tools are much easier to expend than old-style sniffers and guesswork, and they're much easier to complicated to applications developers. Read this technical tip to learn about them and to decrease the time that your network staff has to invest in application diagnosis.

The network is the fresh backplane of a multi-server system; a single transaction often requires the nigh cooperation of multiple servers, databases and appliances connected to one another by network paths. Each of these devices is frequently updated with fresh software, and the network itself is always changing, with fresh paths, fresh switching devices and fresh configurations. It's therefore almost impossible to reproduce a modern multi-server, network-based production system in a test lab. Unfortunately, it's usually the subtleties of the production environment that occasions problems in production applications.

Systems managers must therefore hope that programmers will show in their operations center. Those programmers want to trace an individual transaction through a maze of rig and network paths, but often the tools available in the production environment provide only summary performance metrics and, possibly, some cryptic protocol traces from a few LAN segments. They must either guess at what is happening to individual transactions by looking at the summary data or spend hours trying to find and match up pieces of the transaction current captured by protocol tracing utilities -- an often fruitless exercise, and one that requires protocol erudition that programmers often don't have.

Dye tracing, which can ensue an individual transaction through multiple servers, gives programmers a familiar diagnostic environment. When comprehensive dye-tracing facilities hold been installed, programmers can watch each program call, its timings, and its parameters, as if the entire process were contained within a single server. They can watch as a synthetic (test) transaction arrives at a server, progresses through the applications software and the database calls, and then generates a response; they can watch individual customer transactions that are having problems to perceive where inside the applications and the servers the rigor or bottleneck is occurring.

Dye tracers cost money; they require software to breathe inserted into production servers, which adds complexity. There is likewise a small performance penalty. For those reasons, some production organizations resist their use. But reflect of the time and endeavor saved when there's a problem! Programmers intuitively understand a dye tracer; it's similar to the tools they expend in development. They can find a problem quickly, with much less involvement of the network operations staff and without the necessity to obtain protocol traces quickly during a head -- which may itself occasions problems. The development group may even breathe willing to share the cost of the dye-tracing system, and they may want to expend it during development to tune their applications -- which will likewise manufacture them familiar with it when a head occurs.

A dye-tracing system works by inserting a software shim between the application programs and the underlying operating system. In some dye tracers, that shim watches everything of the program calls, records their response time, and may likewise copy some of the convoke parameters, such as SQL queries. To trace a process from one server to another, some dye-tracing shims can insert a tracking number into inter-processor messages. The shims in the different processors then expend that tracking number and remove it from the messages before they're seen by the applications program. The entire dye-tracing system is completely transparent to the application.

Dye tracers impose a slight load on the server systems, usually a very few percent. To decrease the load further, the dye-tracing system can normally breathe used on only a few servers in a load-distributed environment, for only a restricted percentage of transactions, or only for tracing synthetic measurement transactions.

Different varieties of dye tracers are available from a growing number of suppliers. Examples of these tools, everything with different capabilities, are CA's Introscope Transaction Tracer, HP's Transaction Analyzer, IBM Tivoli's Composite Applications Manager, OpTier's CoreFirst, Quest Software's PerformaSure, and Symphoniq's TrueVue.

ORLANDO, FL -- (MARKET WIRE) -- 05/21/07 -- impact 2007 -- Thousands of IBM's (NYSE: IBM) customers and business Partners are gathered this week for IBM impact 2007, IBM's inaugural worldwide customer event focused on advancing the $160 billion opportunity for service oriented architecture (SOA) through education and demonstrable business results. More than 4,500 IBM customers hold modeled their businesses around SOA, a business strategy that helps a company reuse existing technology to more closely align it with business goals, helping to result in greater efficiencies, cost savings and productivity.

In addition to addressing the serious SOA IT skills shortage, IBM is likewise announcing fresh software and services at IMPACT. Further, more than 100 IBM customers including Cardinal Health, Wachovia and Royal Caribbean will share experiences on how an SOA strategy has made an impact on their businesses to breathe more innovative, supple and efficient. The week-long event likewise features more than 400 sessions targeted to four key audiences: business leaders, information technology (IT) executives, technical communities and the roles that intersect business and IT.

"SOA has been a growth engine for IBM as well as their customers because it gives companies the much-needed flexibility to focus on achieving business results without being hindered by the constructs of established infrastructures," said Steve Mills, senior vice president, IBM Software. "IBM's differentiation is in its aptitude to address business challenges using the privilege equilibrium of business and technical skills along with an unmatched, multi-pronged approach to meeting customers' needs."

Using Serious Gaming to nigh the SOA Skills Gap

A recent study organize that 56 percent of IBM customers cited lack of skills, mainly individuals with a blending of IT technical understanding and business process acumen, as the leading inhibitor to SOA. To address the SOA skills shortage, IBM is announcing fresh tools and certification programs to support organizations develop teams of individuals with so-called "T-shaped" skills, which encompass both deep business skills, represented by the horizontal line of the "T," and technical understanding, represented by the vertical line. They include:

-- A new, interactive SOA game called Innov8: A BPM Simulator, an
interactive, 3-D educational game simulator designed to bridge the gap in
understanding between IT teams and business leaders in an organization.
This type of serious gaming -- simulations which hold the spy and feel of
a game but correspond to non-game events or processes such as business
operations -- has emerged as a successful mode to retrain or develop new
skills. This simulator is a result of the annual IBM SOA case study
competition among graduate students at Duke University and the University
of North Carolina. The game, which is played with a joy stick, is based on
advanced, commercial gaming technologies and allows players to visualize
how an SOA affects different parts of the organization. Together, users can
literally perceive business processes, identify bottlenecks, and explore 'what
if' scenarios before the SOA is deployed.
-- Additionally, IBM is launching "IBM TV: impact Channel," an online
portal that contains webcasts, podcasts, demos, white papers and other
resources targeted to business and IT professionals as well as those
looking to develop T-shaped skills.

IBM has enhanced its SOA certification and education programs with new, self-paced and instructor-led courses conducted online and in classrooms. With more than 218 SOA-based courses for every flush in an organization, IBM's SOA curricula provide the roadmap to master the most highly sought-after SOA industry skills. IBM likewise continues to foster relationships with higher education institutions and is working with hundreds of colleges and universities around the world on SOA curricula.

Bridging IT and Business

To support companies succeed through the various stages of SOA evaluation and deployment, IBM is announcing eight fresh industry-specific SOA Roadmaps spanning six industries.

Each of the SOA roadmaps contains a business blueprint, which helps customers map the business side of an SOA strategy, and an industry-specific framework, which includes core technology used to execute the business blueprint. The fresh SOA Roadmaps focus on critical business process areas within a given industry. Some examples involve online booking for the insurance industry, member enrollment and benefits/eligibility for healthcare, payments for banking, personal shopping for retail, service provisioning and service delivery for telecommunications and supply chain collaboration for industrial.

The business blueprints launch with particular research that outlines industry challenges and how those industries can capitalize from SOA. Each piece of research examines specific business scenarios, describing how those processes are typically executed today and how they could breathe improved with SOA. The business blueprint likewise recommends an SOA entry point to manufacture it easier for businesses to know the best spot to start to deliver the most immediate business benefits. IBM's SOA entry points manufacture it easier for customers to approach and initiate SOA projects. The three business entry points involve people, process and information. The two technical entry points involve connectivity and reuse.

The IBM SOA Industry Frameworks involve technology from IBM and IBM business Partners to support expend SOAs. They provide customers with reusable, industry-specific software modules called business services based on the WebSphere business Services Fabric that accomplish individual tasks tailored to the industry's users, policies and methods. fresh SOA Industry Frameworks are specific to the banking, healthcare, telecom, retail, and insurance industries to add to the first framework for Product Lifecycle Management, which was announced late eventual year. Additional frameworks will ensue later this year.

IBM is likewise announcing six fresh SOA professional services focused on SOA Diagnostic, SOA Strategy, SOA Implementation Planning, business Process Management Enabled by SOA, SOA Design development and Integration, and SOA Management. fresh capabilities involve infrastructure and strategy workshops for SOA Strategy professional services, web application and portal infrastructure services for SOA Design, development and Integration and a fresh testing heart of excellence for SOA management.

New Software and Services

The fresh technologies and services being announced today align to customer entry points to SOA -- people, process, information, connectivity and reuse -- as well as support vertical industry, business process management and governance strategies.

IBM has successfully integrated technology from the recently acquired IBM DataPower SOA appliances and FileNet Content Management and business Process Management (BPM) software into the IBM SOA portfolio. fresh offerings being announced today involve the WebSphere DataPower Integration Appliance XI50, which now supports direct database connectivity including IBM's DB2 data server extending the XI50's enterprise service bus capabilities. It likewise adds support for WebSphere Transformation Extender design studio providing common data transformation tooling across IBM's ESB portfolio. The XI50, along with a fresh version of the WebSphere DataPower XML Security Appliance XS40, now integrates with the IBM WebSphere Service Registry and Repository (WSRR) to offer enhanced governance capabilities and ameliorate service interoperability, reuse and connectivity.

IBM has likewise integrated the capabilities of WebSphere software with the FileNet business Process Manager. IBM Classification Module for IBM FileNet P8 delivers content classification as a service helping automate processes and decision-making to determine how a piece of content should breathe used. Both products can now breathe used in conjunction in the same environment. This allows business analysts and other non-IT staff to model business processes, document them and communicate them across the organization.

IBM has likewise enhanced its SOA portfolio for governance, information management and BPM, and has developed fresh software for protecting an organization's existing IT investments.

New products for BPM involve industry-specific templates with key methodologies and predefined configurable dashboards, which enable users to monitor business activities and adjust accordingly. Expanded business Activity Monitoring software includes adapters that monitor activity from a variety of sources, including third party software, providing a single comprehensive view of business activity across an enterprise regardless of individual IT systems. Additionally, fresh BPM dashboards are now available to track and monitor the roles of people associated with a given activity.

IBM's SOA governance strategy focuses on the overall process needed to govern the SOA environment. It includes an end-to-end registry and repository strategy built around federation of registries. For services in production, the IBM WebSphere Service Registry and Repository (WSRR) software helps customers manage services and shared business processes. fresh features of WSRR focus on assisting in getting started quickly with fresh samples and templates and enhanced SOA Governance support. In addition, integration with IBM's Tivoli Composite Application Manager (ITCAM) offers fresh applications management dashboards, business reporting and chargeback capabilities.

To further ameliorate SOA governance with Service Lifecycle Management, IBM is introducing the IBM Rational Asset Manager. The Rational Asset Management is a registry of design, development and deployment related assets, such as services. This fresh collaborative asset management software gives organizations the aptitude to identify, manage and govern the design, development and consumption of services in SOA. Using IBM Rational Asset Manager allows organizations to reduce development cost and time; securely communicate across disparate global teams and eradicate rework with asset-traceability and utilization monitoring; and accelerate service delivery.

Technical Entry Points: Connectivity and Reuse

To further simplify Web services development, a fresh WebSphere Application Server feature pack is available. It includes wizards and dedicated editors to support users more easily build and reuse web services.

To support customers' needs for supporting an SOA on a mainframe, IBM is introducing a fresh version of WebSphere Process Server on System z. This fresh software automates people and information-centric business processes and consolidates mission critical elements of a business onto a single system. The WebSphere Application Server and Process Server, combined with the recently announced DB2 9 for z/OS, to deliver System z based process and data services for SOA.

Why wait until meltdown, finger-pointing, and stale pizza grasp over your world as a system manager? You can pre-plan what you're going to Do and manufacture your life a lot easier. There are five useful structure blocks that can support you to construct a successful incident management plan:

Configuration database and audit

External experts

Triage (Quick incident isolation)

Instrumentation

Dye tracing

Using these structure blocks and a skilled head manager, you should breathe able to create a more smoothly-running system that handles both routine incidents and intricate problems with less stress.

Configuration database and audit

A single, unified configuration management database (CMDB), completely up to date, is extremely valuable. They can quiz it for the changes made in well-known components just before failure occurred; they can quiz it what will befall if they grasp a particular constituent down for maintenance.

In the actual world, unfortunately, there almost certainly isn't a CMDB. Therefore, the system manager should start the organization on the path to CMDB implementation -- which, by the way, will almost certainly require severe penalties for any staff who manufacture changes without entering it in the CMDB.

With or without the CMDB, all-encompassing and daily audits are a critical tool.

All major applications should breathe reviewed regularly by the all-encompassing audit to detect their dependencies and bring documentation up to date. If some mission-critical application depends on a cheap PC stored under someone's desk, or is running only because operations has written a PERL script to nudge it along, it's better to ascertain that before there's a crisis.

Then, at least once a day, a quick audit of the network and system configuration should breathe made to detect any changes or out-of-specification configurations or measurements. For example, the NetMRI tool from Netcordia can find and document changes in network topology and in the configuration of network elements. It can likewise sprint scripts to ascertain incompatible configuration changes. Similar tools are available for servers and other system components. The key credit is to find configuration changes before they interact with subsequent failures to create a major meltdown. Even if their impact is not recognized immediately, documenting the change will support troubleshooters when a problem occurs.

External experts

Few organizations hold the expertise in-house to wield extremely intricate problems. When those appear, external diagnostic experts who understand many different system components in depth and who are experienced with many different meltdown situations are invaluable.

To find these experts, quiz within your local community and quiz major vendors who they expend when they hold a multi-vendor problem. Bring in the experts to work with your staff while setting up your plans for system instrumentation and for triage, then rescue them on retainer to wait until you hold your next problem that you can't solve without outside help.

Triage (quick incident isolation)

There are three goals for triage:

Recognize well-understood incidents (and the quick fix for them!)

Isolate subsystem problems to the amenable organization credibly

Recognize complex, major-crisis problems quickly

The operations staff should breathe trained to recognize and fix commonly-occurring incidents quickly. Even if they don't recognize an incident, it is often viable to sequester it to a particular subsystem if confiscate metrics are available. For example, synthetic transaction agents can repeatedly test the DNS, everything access paths to the Internet, the availability and performance of critical VLANS, the response time of major database queries, and many other functions. Overhead is minimal, but these metrics can breathe extremely valuable in decreasing finger-pointing and in helping the operations staff quickly sequester an incident and convince the amenable group to grasp responsibility without needing to spend a lot of time arguing. If it's too difficult to create these metrics on your system, maybe your system needs to breathe redesigned. (Otherwise, it will breathe even more difficult to sequester a problem when you're in the middle of a meltdown and no one has slept for two days!)

If the operations staff doesn't recognize a problem as being one of the commonly-occurring incidents, and if it can't breathe quickly isolated to a particular subsystem, then it's time to realize that a major head may breathe brewing. The staff should alert the head manager, notify everything concerned programmers and diagnostics experts that they may breathe called in soon, and start any special trace or measurement facilities that hold been designed for these troublesome situations.

Triage plans and their associated metrics and baselines should breathe designed by the same groups who are asked to respond when there's a meltdown: the operations staff, network designers, server and middleware staff, developers, security staff, system architects, and any external experts who might breathe called in.

Instrumentation

The tools for taking measurements are readily available from many vendors, and many tools are embedded in devices and systems that enterprises already own. For example, everything Cisco routers hold Cisco's IP-SLA measurement tools, and F5 load balancers hold extensive test tools to evaluate server performance. There are likewise worldwide services, such as those from Gomez and Keynote, to test systems that provide services accessible from the public Web.

Within the enterprise's systems, it's well-known that test tools are familiar, that everything passwords are known, and that the tools are easily connected to confiscate test points. It's a actual time-waster when a test "spanning port" is difficult to configure or, worse, already has a cable plugged into it. (What happens if that cable is disconnected to allow attachment of a test device? What other thing will fail?) Vendors such as Apcon provide intricate patching switches for testing; simpler multi-port taps are likewise available.

Be sure that applications log everything errors they encounter, and that the log messages hold accurate time stamps and transaction identification information. Tools such as Splunk can breathe used to scan logs quickly to find viable indications of the understanding for system failure. penniless handling of intermittent connection failure is a very common occasions of system failure (for example, the system may freeze with one quit thinking that a connection is up while the other quit thinks it is down); how will that situation breathe detected and reset?

Dye tracing

Because it's almost impossible to reproduce a modern multi-server, network-based production system in a test lab, and because it's usually the subtleties of the production environment that are causing a intricate incident, system managers must hope that programmers will show in their operations center. Those programmers will breathe trying to trace an individual transaction through a maze of rig and network paths. (In effect, the network is the backplane of a huge multi-server computer system.) Presenting them with simple protocol traces isn't an efficient solution.

Dye tracing, which can ensue an individual transaction through multiple servers, is often worth the cost of installation and the additional overhead, because it gives programmers a familiar diagnostic environment. They can watch each program call, its timings, and its parameters, as if the entire process were contained within a single server. Examples of these tools are CA's Introscope Transaction Tracer, HP's Transaction Analyzer, Quest Software's PerformaSure, IBM Tivoli's Composite Applications Manager and Symphoniq's TrueVue.

Conclusion

Simple metrics and procedures can detect and categorize ("triage") many performance incidents to assist in rapid service restoration, while intricate incidents can breathe handled by specialized tools, such as dye-tracers, and pre-planned management strategies under the supervision of a trained head manager. In some intricate cases, the assistance of external experts who are already familiar with the system is invaluable. These experts should support design the triage metrics and the diagnostic tools -- then breathe placed on retainer to await problems that require their aid.
